The invention relates to a front landing gear of a small unmanned aerial vehicle. A guide rod is arranged coaxially inside the outer cylinder, and a lower inner cylinder, a first-stage spring, and an upper part are sequentially arranged in the cavity between the outer cylinder and the guide rod from bottom to top. Inner cylinder; there is a tire under the outer cylinder, and the upper end and side of the rocker wheel fork of the tire have a set of connecting lug joints respectively, the lug joints at the upper end are connected with the torque arm, and the lug joints at the side end protrude from the lower inner cylinder. end connection; there is a secondary spring on the limit platform at the bottom of the lower inner cylinder, the secondary spring is in contact with the bottom end surface of the clamping joint that is slidingly connected to the outer cylinder, and an ear piece is provided on the outer circumference of the clamping joint, and the torque arm The upper end of the upper end is connected with the lug; a top support is provided at the end of the upper inner cylinder protruding from the outer cylinder. The fixed-frame semi-rocker front landing gear of the landing gear improves the stability of the aircraft's taxiing, take-off and landing, and maintainability, and fully absorbs landing impact energy.
Description
technical field [0001] The invention relates to a front landing gear of a small unmanned aerial vehicle, which is especially suitable for an aircraft with a small space at the head part. Background technique [0002] With the development of small and medium UAV systems, UAV technology is being widely cited. The take-off and recovery methods of small and medium-sized UAVs are limited by conditions, and most of them are ejection take-off and parachute recovery. However, when conditions permit, the way of take-off and landing is optimal. However, the roll take-off and roll landing have relatively high requirements on the cushioning, shock absorption and roll stability of the landing gear. Currently, the simpler off-the-shelf nose gear used on smaller drones is not suitable for mission-specific drones with tight nose spaces. Its reliability is poor, the cushioning and shock absorption effect is not good, and defects and faults are not easy to be found. Contents of the invent...
